VEHICLE-SPRING LUBRICATOB.

Application filed February 12, 1917.

To all whom it may concern:

Be it known that I, Tnrooonn C. Scnor'rzr, a citizen of the UnitedStates, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements in Vehicle-Spring Lubricators; and I do declare the following to be a full, clear,and eXact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates broadly to lubricating devices and morespecifically to those designed for use on the leaf springs ofautomobiles and similar vehicles.

The principal object of the invention is to provide a very simplyconstructed lubricatingdevice which can be very inexpensivelymanufactured and yet which will be extremely etlicient in operation.

A secondary object is to provide a device of this character which may beadjusted to springs of various widths.

Still another object is to provide means whereby the device may beprovided with one or more reservoirs for storing a quantity of oil sothat it will be unnecessary to give any attention to the device exceptat extended intervals.

\Vith the above and many other objects in view the invention resides inthe novel features of construction and combination of parts which willbe hereinafter more particularly described and claimed. and shown in thedrawin wherein 1 Figure 1 represents a. vertical cross sectional viewthrough an automobile spring having my lubricator applied thereto, thelatter being shown in edge view;

Fig. 2 is a side elevation of the invention applied to a spring;

Fig. 3 is a vertical transverse sectional view on the plane of the line3 3 of Fig. 2;

Fig. 4 is an inner side view of one of the side members of the device;

Fig. 5 is a detail perspective view of the combined]reservoir andfilling member.

For the purpose of illustration this inrproved luln-icator is generallyapplied to an ordinary vehicle spring of conventional design composed ofa plurality of leaves L. Broadly the invention comprises a pair oflubricating members 1, disposed one on each side of the spring S. acombined reservoir and filling member 2 and means for bold ing the partstogether and to the spring.

Specification of Letters Patent.

, Patented Apr. 16), il ifl.

Serial No. 148,130.

Each of the lubricating members 1 consists of a substantiallyrectangular casing 3 formed of metal or the like and having one openface which is disposed toward the edges of the leaves L, and a pad l ofcompressible material such as felt or the like which will hold the oiland feed the same as it is required between the several leaves L. Theupper and lower ends 5 and 6 ot' the casing 3 are somewhat wider thanthe sides 7. the former being wider than the thickness of the pad il:while the latter are less in width than the thickness of said padthereby allowing the pad to be pressed tightly against the edges of theleaves of the springs. The upper and lower ends project over the top andbottom leaves L as shown in Fig. 3.

In order that the two lubricating members 1 may be securely held inplace on the spring t), upper and lower ears 8 and 9 are formed on eachof said members, said ears extending outwardly from the inner edges ofthe ends 5 and 6. The lower ears 9 are apertured to receive a clampingbolt 10, which together with the nut 11 thereon holds the lower portionsof the lubricating members.

Each of the upper ears 8 forms one side of a chamber 12. the upper end 5forming the bottom, while a. sheet metal piece soldered or otherwisesecured in position forms the other parts. The walls of this chamber ineffect form a hollow ar, and the inner and outer walls thereof areprovided with alined openings to receive a bolt 13. the outer openingsof the ears being substantially the same. diameter as the bolt. whilethe inner openings it are somewhat larger in diametn'.

Before placing the bolt 13 through the alining openings in each of thehollow ears, the combined tubular reservoir and filling member 2 isplaced in position. said reservoir having its ends tapered as shown at15 and disposed in the enlarged openings 14.-

ll hen the bolt extended through the. openings in the ears and throughthe reservoir and the nut 16 tightened. the upper end portions of thelubricating members will he forced toward each other, thereby pressingthe pads 4: into engagement with the sides of the spring. When the bolts10 and it} have been properly adjusted the device will be ready to havea. suitable lubricating fiuid inserted.

in the impeaportion of the res ervoir 52 substantially midway its endsforms a filling opening in which oil may be poured to be distributed tothe pads l. It will be noted that the oil runs in both directions fromthe center of the reservoir and out the open ends thereof into thehollow ears or chambers 12, from whence it passes down through openings18 in the ends 5 into pas sageways 19 which communicate withsupplemental reservoirs 20. The latter reservoirs are formed by pressingthe faces of the members 1 outwardly to provide depressions in which oilwill collect to be distributed to the pads 4 which will feed it betweenthe leaves of the spring when necessary. As a matter of convenience instamping the casings 3, the reservoirs 20 are preferably circular inside elevation.

From the foregoing description taken in connection with the accompanyingdrawing it will be obvious that a very simply constructed lubricatingdevice has been devised. The simple nature of the different parts of thedevice readily allow them to be formed of sheet metal or similarmaterial and at a slight cost and furthermore, the several parts may bevery easily and quickly assembled upon approximately any ordinary formof vehicle spring.

I claim as my invention:

1. A device of the class described comprising a pair of lubricators, ahollow ear on one end of each, a tubular reservoir coir necting saidhollow ears and communicating with the interior thereof, and a boltconnecting the ears for holding the parts together.

2. A device of the class described comprising a pair of lubricators, ahollow ear on each, each of said ears having an opening in its innerface, a tubular reservoir having tapered ends disposed in said openingsand communicating with the interior of said ears, and a bolt connectingthe ears for holding the parts together.

3. A device of the class described comprising a pair of lubricators, ahollow ear on one end of each, each of saidears having alined openingsin its inner and outer faces, a cylindrical tubular reservoir having itsinner ends disposed in inner adjacent openings in its ears, and a boltextending through said openings and the reservoir for holding thelubricators and the reservoir together.

el. A device of the class described comprising a pair of lubricators, ahollow ear on one end of each, a tubular reservoir connecting said earsand communicating with the interior thereof, a bolt connecting the earsfor holding the lubricator and reservoir together, a supplementalreservoir in each of said lubricators formed by pressing the face of thesame outwardly, and a passageway connecting each of said hollow earswith the adjacent supplemental reservoir.

A device of the class described comprising a pair of lubricators, eachformed of a substantially rectangular casing, their upper and lower endsbeing wider than the sides, an ear formed on each end of each casing, achamber connected with one ear of each casing, each of said chambershaving alined openings formed in its inner and outer walls, acylindrical tubular reservoir having tapered ends disposed in theopenings in the inner walls of said chambers, a bolt extending throughsaid alined openings and the reservoir, a second bolt connecting theother ears and a lubricating pad disposed in each of said casings, saidpad being thicker than the width of the sides of the casing.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
